PHP - 在同一个文件上多次运行相同的php函数

时间：2014-07-04 02:52:26

标签： php

我目前正在创建一个数据库/表列表系统，它将显示用户当前喜欢/不喜欢的内容。获取用户的喜欢/不喜欢，并通过名为displayRating()的单独文件中的函数进行管理。我使用require_once来调用它所在的单独文件，在我的列表的开头，然后开始工作。

然后继续我的

foreach(...){
...
displayRating($id);
...
}

但是我收到了错误，这似乎告诉我，我无法在同一页面内多次调用函数。这是我的确切（未优化）代码：

vote.php 

<?php
function displayRating($id){
    if(isset($id)){
        require_once('medoo.min.php');
        // Start up the D.B. Connection
        $database = new medoo([
        // required
        'database_type' => 'mysql',
        'database_name' => '****',
        'server' => 'localhost',
        'username' => '****',
        'password' => '****',
        'charset' => 'utf8',
        // driver_option for connection, read more from http://www.php.net/manual/en/pdo.setattribute.php
        'option' => [
        PDO::ATTR_CASE => PDO::CASE_NATURAL
        ]]);
        // xf_user_field_value DB. Amount of ratings: 506c617965725f7261746573    Current Score: 706c617965725f726174696e67
        $accountinfo = $database->select('xf_user_field_value', ['field_value'], ["user_id"=>$id]);
        $vScore = $accountinfo[5]['field_value'];
        // Processing Time
        $phrase = '<div class="bc"><div data-hint="%1$s" class="hint--right vote %2$s"></div></div>';
        if($vScore == 0){
            printf($phrase, 'Neutral Score', 'v_equal');
            return;
        } elseif ($vScore > 0){
            // Positive Here
            switch($vScore){
                case 1:
                    printf($phrase, '1 Like', 'v_p1 hint--success');
                    break;
                case 2:

                case 4:
                    printf($phrase, '4 Likes', 'v_p4 hint--success');
                    break;
                case 5:

        } elseif ($vScore < 0){

对于那些热衷于此的人来说，这是一个确切的错误 - 我已经对这里的一些内容进行了混淆，因为我正在通过实时安装工作：

致命错误：无法重新声明/ home / ** / public_html中的displayRating（）（之前在/home/**/public_html/**/vote.php:2中声明）第68行/ ///strong>/vote.php

3 个答案:

答案 0 :(得分：0)

这似乎是在发生这种情况，因为在你的test.php代码中，你包括了带有

的vote.php

需要（＆＃39; vote.php＆＃39）;

并且您还需要＆＃39; displayCodes.php＆＃39;在test.php中

这里的问题是你也打电话给'displayCodes.php＆＃39;在vote.php里面，所以函数被声明了两次。尝试在test.php中注释这一行

需要（＆＃39; displayCodes.php＆＃39）;

这样你只需要包含一次这个功能。

希望这有帮助

答案 1 :(得分：0)

displayCodes.php和test.php都需要vote.php，后者没有执行require_once。将test.php切换到require_once（＆＃39; vote.php＆＃39;）;

答案 2 :(得分：0)

尝试删除displayRating（）方法中的require_once('medoo.min.php');。你将displayRating（）调用到一个循环中，所以它可能会多次包含medoo.min.php。
